Summary
Penile cancer is primarily squamous cell carcinoma, often linked to phimosis. Early-stage diagnosis and treatment significantly improve survival rates for this rare cancer.
Area of Science:
- Oncology
- Urology
Context:
- Retrospective analysis of 42 penile cancer cases at Gunma University Hospital between 1961 and 1985.
- Average patient age was 56.9 years, with a median diagnostic delay of 9 months.
- Common symptoms included masses, pain, ulceration, and urinary stream abnormalities; over 75% had phimosis.
Purpose:
- To analyze the clinical characteristics, treatment modalities, and survival outcomes of penile cancer patients.
- To evaluate the impact of disease stage on patient prognosis.
Summary:
- All 42 cases were squamous cell carcinoma, staged according to Jackson's classification (31% Stage 1, 29% Stage 2, 38% Stage 3, 2% Stage 4).
- Treatments included surgery (37 patients), chemotherapy (23 patients, primarily bleomycin/peplomycin), and irradiation (26 patients).
- Five-year survival was 77% overall, 92% for low-stage (1-2) and 63% for high-stage (3-4) disease.
Impact:
- Demonstrates the effectiveness of multimodal treatment for penile cancer.
- Highlights the critical role of early detection in improving survival rates, with significantly better outcomes for early-stage disease.
- Provides valuable long-term survival data (5- and 10-year) for penile cancer management.
